lineis vermiformibus pallidis pictus ; ad angulum spira? duplicating 

 stratus, infra medium striatus ; apertura rubescente (f. 304). — 

 The angle of this not very characteristic shell is double-striated, 

 and the lower part is striated.

 — Short, solid, white, sometimes spotted, sulcated near the base. 



157. perplexus, Sowb. — C. brevis, subturbinatus, lsevis, fasci- 

 atim creberrime punctatus (f. 324). — This shell perplexes me, 

 because there is a variety of C. puncticulatus which it nearly re- 

 sembles. This, however, is quite smooth, and more angular.

 rubro interruptim lineatus, infra crenulato-sulcatus ; fauce vio- 

 lacea (f. 325, 326, 398). — The latter represents the type, and 

 agrees with the figure referred to by Lamarck, and also with the

 with the least inclination to " puce " in the aperture.

 atus, fasciis latis flavidis bifasciatus (f. 305). — Sharply angled, 

 striated at the base, with two broad yellowish bands. 



162. viridis, Sowb. — C. parvus, tenuis, obtusus, kevis, fasciis 

 irregularibus latis bifasciatus ; spira striata, obtusa ; lateribus con- 

 vexis (f. 102). — It is thinner and narrower than C. Rattus.

 tricosis, fuscus ; spira et fascia mediana albis, castaneo maculatis 

 (f. 281 and 415). — The white central band and the white spire 

 are spotted with dark chestnut. 



164. corallinus, Kien. — C. quam C. Cumingii angustior, fas- 

 ciis griseis transverse fusco-lineatus (f. 416). — Narrower than 

 C. Cumingii, with elevated spire, and cross-lines on the greyish
